Intermetallic TiAl-based alloys represent an important class of light weight and high temperature structural materials, ideal for future aircraft engines, and can replace the extensively used Nickel based super alloy Inconel 718. However, due to their improved strength, the manufacturing of components from conventional machining processes is nearly impossible and results in high tool wear.Advancements in wire electric-discharge-machining (wire-EDM) technology has made it possible of machining hard materials with accuracy, confirming to quality standards, meeting production targets,ina flexible and inexpensivemanner. In Germany,recent research on wire-EDM of Inconel 718 hasshown negligible white layer and an acceptable fatigue performance,for fir tree slot production in jet engines. This paper analyzesthefeasibility of wire EDM as the machining process for gamma Titanium aluminidesfor future jet engine components.
